The essence of the Return-to-Void Realm lies in the Sun God Dharma Image replacing the physical body and merging into the heavens and earth, with the Sun God Dharma Image acting as the medium to fully control the power of the heavens and earth.
Once one steps into this realm, one fully possesses the might to transform the heavens and the earth and change the colors of mountains and rivers.
The Return-to-Void Great True Being has transcended the cognition of ordinary cultivators, but the source of all this is the power of the heavens and earth controlled by the Sun God Dharma Image.
Only when the essence of the Yang God is strong enough and pure enough can it forcibly plunder the heavens and earth with its own power.
In weaker worlds, the more power of the heavens and earth the Return-to-Void Great True Being can plunder, the stronger their own strength becomes.
